API 5L X52 cold expanded steel pipes chemical compositions
API 5L X52 cold expanded steel pipes shall be randomly checked for straightness; deviation from a straight line shall not exceed 0.2% of the length. Measurement may be made using a taut string or wire from end to end along the side of the pipe, measuring the greatest deviation.API 5L PSL1, PSL2 X52 cold expanded steel pipes have accomplished a permanent increase in outside diameter or circumference of at least 0.3%, throughout its length, by internal hydrostatic pressure in closed dies or by an internal expanding mechanical device.
